I recommend this room which is actually a double one (bed and living room)! I have really appreciated my 10 days spent in Bangkok. I was there for completing a graduation program with a group. I organized there some fruitfull working groups thanks to the large living room and the great wifi connection.
Lalida is a very nice host, ready to help with quick answers.
About the surrounding, the flat is near BTS stations (Nana and Phloen Chit) and located in a very active neighborhood.
In the tower, you will find small shops, restaurant and a swimming pool.You will definitely enjoy your stay here.
